ELIVOOD C, PHILLIPS, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-FOURTH TO OSCAR A. SCI-IEIBE, OF CHICAGO, ILLINOIS.

BARREL BUNG'AND BUSHING.

SPECIFICATION forming part of Letters Patent No. 706,103, dated August 5, 1902.

To all whom, it may concern:

Be it known that I, ELwooD O. PHILLIPS, a citizen of the United States of America, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Barrel Bungs and Bushings, of which the following is a specification.

The present invention relates to that type of bungs for barrels and like wooden-vessels in which an exterior screw-threaded bushing is rigidly screwed into the barrel-orifice and is also interiorly screw-threaded to receive a screw-threaded closure cap or plug.

The object of the present improvement is to provide a simple, convenient, and durable construction and formation of parts whereby an efiective seating for the closure-plug is provided and the corrosion of the lower surface ofthe same prevented, and the consequent contamination of the contents of the barrel by such corrosion, all as will hereinafter more fully appear, and be more particularly pointed out in the claim. I attain such object by the construction and arrangement of parts illustrated in the accompanying drawings, in which Figure 1 is a longitudinal sectional elevation of a barrel bung and bushing embodying the present improvements; Fig. 2, a side elevation of the parts in a detached condition; Fig. 3, a plan view of the closure-plug; Fig. 4, a plan View of the elastic bottom cover or head of the closure-plug.

Similar numerals of reference indicate like parts in the several views.

Referring to the drawings, 1 represents the usual exteriorly-screw-threaded bung-bushing screwing into the stave 2,0r other portion of the barrel and provided with a marginal projecting flange 3 to insure the proper position of the bushing in the barrel-stave and at the same time protect the edges of the barrel-orifice. The interior of r the bushing 1 is also screw-threaded to receive the closureplug, and the upper end of the bushing is formed with an annular recess or countersink 4 to receive the head or flange of the closureplug. I

In the present improvement the lower end of the bushing 1 is provided with an inturned annular flange 5 to form a seat for the lower end of the closure-plug, as hereinafter more fully set forth.

6 is the closure plug, exteriorly screwthreaded to fit the bore of the bushing 1 and formed with a central cavity 7, in which in turn is formed a cross-bar that affords an engagement for a wrench in screwing the closure-plug into or out of place.

The closure-plug 6 at its upper end is formed with a marginal .head or flange 8, fitting the countersink 4 of the bung-bushing, so as to afford an even top surface of both bushing and plug. At its lower end the closure-plug is provided with a central downwardly-extending shank 9, having at its lower end a button or head 10 for the purpose hereinafter stated.

11 is an elastic button-cover for the lower end of the closure-plug and made of a disk shape, so as to seat itself upon the upper surface of the marginal inturned flange 5 of the bung-bushing to effect a seat at such point.

In the present invention the central portion of the elastic cover or disk 11 is formed with a closed bottom recess 12 of a shape corresponding to that of the shank 9 and head or button 10 of the closure-plug and is adapted to be forced upon the same to effect a substantial attachment of the cover or disk to the closure-plug and yet permits of a subsequent detachment and replacement when required.

Having thus fully described my said invention, whatI claim as new, and desire to secure by Letters Patent, is-

In a barrel bung or bushing of the character herein described, the combination of a stationary bushing formed with a lower inturned o margin or seat, a rotatable plug fitting said bushing and provided on its lower end with metal portions of the bung and bushing, sub 10 stantially as set forth.

Signed by me at Chicago, Illinois, this 9th day of June, 1900.

a ELWOOD G. PHILLIPS.
